No MP3 player lineup is complete without a flash memory option. For every hard drive based player sold about 2 flash players are purchased. In a recent interview with Reuters Jason Reindorp spoke of additional devices coming from Microsoft:
"The industry moves in this sort of Christmas to Christmas cycle. So you can expect that there will be more devices, more features in the market at that point," he said.
Players based on flash media are physically smaller and often much less expensive than hard drive based devices. The downside is that storage is often limited to 8 GB or less. Movies and photos are not practical on the small form factor but there is plenty of room for digital music, FM radio and even Wi-Fi file sharing. Why do we think Zune will toss it's hat in the flash arena? It's not really their choice. The market drives consumer electronics and the market likes cheaper flash players.
